Classic Fine Grain Developer

Posted by Monday317 on 17th Jan 2018

Used to mix it up by the gallon, back in the day, and thought it was great with Kodak Panatomic X--especially in 35mm. Being a solvent developer, I wouldn't use it with the current weapon of choice, Acros 100. Looking at the Dark Side of staining developers to see if I like the results. D-23 is still the go-to for many in large-format, especially with traditional grain films like Ilford's and Fomapan, among others. Doesn't have the high acutance and razor sharpness needed for 6 x 6 and smaller, maybe D-76, or some of the newer formulas--especially for t_grain films. Enjoy!

A wonderful developer - Simple and Effective

Posted by Unknown on 28th Jun 2016

I'm a lover of history, well more like obsessed with it. Plus add in my love of trying out new old things from shooting a black powder musket, to using one of the simplest and a historic developer. Developer 23 is a must try for any home developer, produces amazing negatives with tone separation and surprisingly fine grain. While some films you have to shoot a little slower than box speed, it does give a very historic look. This certainly will be added to my kit with my WW2 era combat photographer impression.
